and thus promoting the flow of oil and itfnr The uaturcof this invention consistswhicfly, of a spiral anger blade or. shni't connected, by a. swivel-joint to the dcvicc by which it i5. opcratcd in the tube or pipe designed to be cleaned, whcrcby the said tool is allowed to freely turn and yield to tho obslructiono on zinc interior of the tubcdnring its descent in tho came, and thus provcntthe l'orcingol' solid oh atrnctions toward lhc bottom ofthe tube.

The invention also consicta in thc'combination, with a spiral angcr blade or shall, oi a swivelconncction providcdwith-a clutch for prcvcnting the Emotion of said auger during its withdrawal from tho tnbo, thereby causing the side edges of the spiral to compo the in tcrior surface ofthe tube and carry tho re moved substance to the upper end of the who, and at the same time, by the retraction of the filled spiral, crcati n g avacuum below the spiral,

thcrinorc consists in a pcouliar construction and combination of a link connected at one cad by a swivcl'joint with i the angc'r, and at tho opposite c'nd by a Scrcivcoupling to thc rope or other appliancc by which the anger is manipulated in the tube of the well, all as llercinaftcr more fully described and specifically set forth in the. claims.

After the auger has penetrated the pamfiine the desired depth it is withdrawn from the tubing by means of the mph 1' or other suitable appliancin'; connected to the up l per end of the link a. The draft upon said I Iii} a:igg'er-shank.

The nihresaid operation is repeated until, the bottom of the well lied and the entire length of the tubing cleaned.

11. As a means for cleaning tnblngs of Wells, a spiral shalt or twisted blade connected by a swiyel jointto the appliance by which said shaftor blade is suspended in the tubings aforesaid, snbstantiall as and' i'or the purpose specified.

2. The spiral blade A, in combination with a swivel provided with a clutch for preventin the reverse rotary motion of stantia ly as described, for "forth. f

Thecolnhination of the spiral. blade A, provided with the rigid rod at, having the head (I, provided with iatehet-teeth and the link 0, conneoted by swivelg'oint with the said rod and prm-ided with a catch adapted to engage the ratchet aforesaid, substantially as specified and shown.

4. The combination of the spiral shaft A, the link c,'c0nneeted therewith by a swiveljoint and provided with a clutch for preventing the reverse rotary motion of the shaft A, and the rope a", connected to the link. 0 by the socket a, substantially in the manner described and shown. l
